“If you merely repress a temptation or this first motion of sin within you, it will probably come up again still more strongly. To that extent I agree with the modern psychology. Repression is always bad. “Well, what do you do?” asks someone. I answer: When you feel that first motion of sin, just pull yourself up and say, “of course I am not having any dealings with this at all.” Expose the thing and say, “This is evil, this is vileness, this is the thing that drove [Adam] out of Paradise.” Pull it out, look at it, denounce it, hate it for what it is; then you have really dealt with it. You must not merely push it back in a spirit of fear, and in a [cowardly] manner. Bring it out, expose it, and analyze it; and then denounce it for what it is until you hate it.
